This invention relates to therapeutic appliances.

lt will be explained as embodied in instruments adapted for the application of radiant energy, particularly ultra-violet light rays, in the treatment of diseased conditions in body cavities. V

Light rays, both visible and invisible, are extensively used in the treatment of certain diseased conditions of the human body. Often the diseased condition is located partly or wholly within body cavities which are more or less curved and Whose walls aremore or less irregular or lie in folds-of tissue. Sometimes a diseased part may be located on the same side of a cavernous cavity as the external opening thereto through which an instrumentmay be inserted. 'lhe usual appliances heretofore employed to direct the light rays from the source where they 'are generated, to the interior of the diseased cavity have consisted of straight or curved rods of quartz. Quartz is a good conductor of light rays, includingthe actinic ultra-violet rays, and the greater part of the rays ordinarily will follow the axis of the rod no matter how much the same may be curved. Consequently, the greater'part of the rays pass out from the end of the rod in relatively straight lines. Such appliances are ineliicient and ineffective in applying the rays to the side walls or folds of a cavity or passage. Furthermore, the light rays are more efcacious when they strike the surface under treatment approximately at right angles thereto, and with the present rods only a relatively small area directly in front of the end thereof (and it may be an area which is not diseased or relatively only slightly diseased) receives the rays at approximately right angles. l sons thus outlined the present light applifcators are inefficient and ineiiective for a plying the light under many conditions. T e object of this invention is to overcome these diiculties.

One of the objects of this invention Iis to provide an improved applicator.

plying light rays to the interior walls of body cavities.

Another obj ect is to provide an applicator whereby the light rays are defiected from their normal path therethrough and projected in the desired direction.

Another object is to provide an a which is elcient, reliable and read' factured. A

Other objects and advantages will hereinafter appear..

low rod of used quartz. The rod or tube is closed at both ends and, if desired, the enclosed space or chamber may be evacuate. The forward or inner end l1 of the rod is rounded. so as to facilitate the forcing of the applicator into bod cavities. The rear end of the rod is encirc ed by a ferrhle. or collar 12 formed from suitable metal, such as brass, which may be shaped to iit a socket in the lamp housing. Fcrrule l2 may be attached to the quartz body by a suitable cement, such as plaster of Paris or litharge cement. A pro- ]ecting lug or ridge 13 may be formed in the quartz to serve as a stop for limitin the extent to which the applicator may be lnserted.

AssIGNoa 'ro man BUBnIcx i he applicator shown in Figures. 1 v`to 3' has an elon ated body 10 formed from a holc 80 FFigure 8 is a section on the line 8-8 of rounded end a-reflector 14 is located. A Reflecp tor 14 may be made of suitable reflecting madierent requirements. It is shown in the f drawing as having a somewhat cone-shaped exterior with the apex toward the rear or lamp end of the rod,-that is, pointing in the direction from which the rays approach it..

:This reflector may be supported and secured 'the rod 1n place within the rod by suitable means. In the drawing it is carried on the forward end of a metal rod or wire lto which it may be soldered or otherwise secured. The rear end of wire 15 is secured to the hub 16 which, by means of spokes 17, is carried at the center of a split metal ring 18. Tliering 18 fits the bore of tube 10 and may be held in place by a ridge 19 formed in the quartz.

Most of the light rays from the lamp Will -pass longitudinally or aiallythroughl thev space in the elongated rod until they encounter the reflecting surface of reflector 14;4

the rays in such a The reflector will deflect way that they will pass outwardly through the quartz wall of the rod as shown in Figure 2 instead of passing out at the end of the rod as was the case with 'prior applicators.

Figure 4 shows a modified construction embodied in a curved applicator. The bod` of this applicator comprises a rod 20 formed of metal, such as brass tubing. The lamp or rear end of the metal tubo is closed and sealed by a quartz plug 21. 22- is fitted into the curvedV forward en o so asto seal the same and, on account of the peculiar property of quartz heretofore mentioned, to direct the light rays around the curve. Suitable cements', such as those previously mentioned, may be used to secure the quartz plug to the inetal tube and theexternal chamber may or may not be evacuated as desired.

The forward end of plug 22 is formed to accommodate any desired shape of reflector 23, such as the inverted cone shown, and this surface is coated with a suitable reflecting material. It has been found that a satisfactory reflecting surface can be' applied to the iliartz as follows: Prepare a solution A by 'ssolving silver nitrate in distilled water; then precipitate the silver with ammonia and finally add suflicient ammonia water to dissolve the silver precipitate. Prepare a solution B by dissolving Rochelle salts in distilled Water and add a smallfamount of silver nitrate solution. The quartz surface to be plated or coated after being thoroughly cleaned and freed of grease, is dipped into a solution composed of equal parts of solutions .A and B.

A hollow rounded-end fused ual-tz tip is fitted upon the exposed end o 24 quartz plug 22 and fused thereto. r1 his tip serves to probe used to good effect in some situations an A fe a l* r 'wherein a reflector A quartz lu ,instead of curve( a smooth rounded end to facilitate the forcing of Athe applicator into a' body cavity. i

The junction o the metal tube 20 and quartz tip 24 preferably should be far enough back rom the reflecting surface so that all or most of the deflected rays can pass out through quartz instead o'encountering Vthe obstruction of the metal tube.

It has been found that when curved quartz applicatorrodsbccome wet, as usually happens, for example when they are inserted. into the throat, the tendency of the rays to follow the axis and pass around the curve is very materially lessened. Under such conditions a relatively large percentage of the rays will continue in `substantially their origin-il direction and will escape from the4 rod at the `curve. The sheathing of the quartz at the curve by the metal tube prevents the saine from becoming wet and preserves the' drv quartz. 4

gures 5 and 6 show another modification 25 shaped somewhat like the bowl of a spoon is located in theforward closed end of a hollow quartz rod 26. Such a reflector will not only deflect the rays out- 4 wardly through the side Walls of the quartz rod, but will scrve to collect and concentrate them into a reduced area and thereby magnify their effect. Reflector 25 may be supported a metal strip 27 and split ring 28 which maybe formed integrally therewith. Figures 7 and 8 show :mother modified type of curved applicator wherein a reflector quartz is utilized to direct the rays around a curve. applicator comprises a quartz rod 30 into the forward curved end of which is fitted and cemented a curved tube 31 of suitable reflect ing metal, such as olished nickel. This reflector serves to defect the rays around the curve. end of the applicator tube may be closed and sealed bya rounded uartz ti 32 .fused to the end ofjquartz tu e 30. chamber within the rod may then be evac uated, if desired.
